I. Preparations before Installation 
Site and environmental requirements 
Foundation load-bearing: The equipment should be installed on a flat and solid concrete floor or a shock-resistant foundation. The load-bearing capacity must be able to accommodate the equipment's own weight (typically 1 - 5 tons) and the impact force during operation, to prevent deformation of the equipment due to ground subsidence. 
Environmental Control: 
Temperature: Maintain a constant temperature of 20 - 25℃ (temperature difference ≤ ±2℃/h). Avoid thermal expansion and contraction of the machine body and molds due to temperature changes, which may affect the positioning accuracy (for example, a temperature difference of 1℃ in metal components may cause a deformation of 0.01mm/m). 
Humidity: Maintain within the range of 40% - 60%. Excessive humidity can cause materials to get damp (such as self-adhesive tapes and films), while too low humidity may lead to static electricity, which can interfere with material transportation and positioning. 
Cleanliness: Keep away from dust and oil sources (such as welding workshops, spray painting rooms). If necessary, install dust covers or clean enclosures to prevent dust from adhering to the mold edges or positioning sensors, which could affect the alignment detection. 
Power supply and air supply: 
Power Supply: Requires an independent circuit for power supply, with stable voltage (380V ± 5%). Equipped with a voltage stabilizer and leakage protection device to prevent voltage fluctuations from causing the servo motor and sensors to malfunction. 
Air source: The pressure of the compressed air should be maintained at 0.6 - 0.8 MPa and must be dried and filtered (with a three-stage filter installed) to prevent moisture and impurities from entering the cylinder or vacuum system, which could cause movement to become sluggish. 
Equipment unpacking and inspection 
After opening the box, it is necessary to verify whether the equipment model, accessories (such as molds, locating pins, sensors) are consistent with the order, and check whether the precision components such as the body, guide rails, and screw rods have any bumps or deformations during transportation (the straightness of the guide rails can be detected using a dial indicator). 
Confirm that all the random technical documents (installation manual, electrical schematic diagram, accuracy verification report) are complete, with a particular focus on the "reference position" of the equipment (such as the coordinate of the positioning hole, the position of the reference line). 
II. Key Precautions During Installation Process 
Equipment level adjustment 
Use a level gauge (with an accuracy of 0.02mm/m) to measure multiple points on the X-axis and Y-axis directions of the equipment's working surface. Adjust the anchor bolts to ensure that the horizontal deviation is ≤ 0.05mm/m. 
Level adjustment should be divided into "coarse adjustment" and "fine adjustment": First, adjust to a roughly level position and run the equipment without load for 1 hour (allowing the components to release stress), then fine-tune to the standard level to avoid horizontal deviation caused by stress deformation after operation. 
The installation accuracy of key components 
Parallelism between the mold base and the worktable: The parallelism between the mold base (the component for installing the mold) and the worktable surface should be ≤ 0.02mm/100mm. A micrometer can be attached to the mold base and moved along the worktable surface for detection. If the deviation is too large, it will result in uneven die-cutting pressure, causing deformation of small holes or edge burrs. 
Verticality of the guiding shaft and the guide rail: The verticality of the feeding guiding shaft (such as the discharge shaft and the receiving shaft) of the equipment to the main guide rail should be ≤ 0.01mm/100mm, to ensure that the material is not deviated during transportation and to avoid the deviation of the positioning reference. 
Mold installation and positioning: 
The small hole molds (such as etching molds and laser cutting molds) need to be fixed by using locating pins or magnetic suction. The alignment deviation between the mold reference edge and the equipment's positioning reference should be ≤ 0.01mm. This can be calibrated with the assistance of an optical alignment instrument. 
The cutting edge of the mold must be kept sharp and free of burrs. Before installation, it should be inspected with a magnifying glass to prevent incomplete die-cutting of small holes due to defects in the cutting edge. 
III. Key Considerations in the Debugging Phase 
Calibration of the positioning system 
Setting of positioning reference: Based on the alignment marks on the material (such as round holes, color marks, or cross lines), adjust the position of the visual sensor (CCD) or mechanical positioning pins to ensure that the center of the sensor aligns with the center of the mark, with a deviation of ≤ 0.005mm. 
Alignment accuracy test: 
First, conduct a trial cutting with the waste material to check the deviation between the position of the small hole of the first piece and the marking of the positioning ring (this can be measured using a two-dimensional imaging instrument). If the deviation exceeds ±0.03mm, the "positioning compensation" function of the equipment (fine adjustment of X/Y axes) needs to be used for correction. 
Carry out 10 - 20 consecutive trial cuts, and statistically analyze the fluctuation range of the positioning deviation. It should be ≤ ±0.01mm (this is the stability requirement for mass production). If the fluctuation is too large, it is necessary to check the synchronization of the feeding mechanism (such as the clearance between the servo motor and the ball screw). 
Pressure and speed parameter calibration 
Die-cutting pressure setting: For small holes (especially those with a diameter of φ≤1mm), the pressure must be uniform and precise. The initial pressure should gradually increase from a low level (such as 0.1MPa) until the small hole is completely cut off without any deformation. Excessive pressure may cause material stretching or damage to the die. 
Matching of feeding speed and die-cutting speed: The feeding speed (e.g. 5 - 30m/min) should be synchronized with the die-cutting frequency to avoid material stretching due to speed mismatch. This can be calibrated through the "electronic gear ratio" function of the equipment's PLC system to ensure that the error in each feeding length is ≤ 0.02mm. 
Material tensile force control 
For flexible materials such as films and tapes, the feeding and reeling tensions (usually 0.5 - 5N) need to be adjusted. If the tension is too high, the material is prone to deformation; if it is too low, the material becomes loose, both of which will affect the positioning accuracy. 
The tension can be monitored in real time using a tension sensor, ensuring that the tension fluctuation range is ≤ ±0.1N. Especially in areas with densely packed small holes, unstable tension can cause the position of the small holes to shift. 
Trial cutting and accuracy inspection 
After the first trial cutting, the following aspects should be carefully inspected: 
Small hole size: The hole diameter deviation (required to be ≤ ±0.01mm) and the perpendicularity of the hole wall (≥ 85°) are measured using a two-dimensional measuring instrument to prevent the hole from becoming conical due to the tilt of the mold. 
Alignment deviation: Measure the relative positions of multiple process die-cutting (such as punching holes first and then die-cutting the shape). The alignment error of adjacent processes should be ≤ ±0.02mm. 
After continuous production of 50 to 100 pieces, 10% of the products should be randomly inspected to confirm the stability of the accuracy. If there is a deviation increase (for example, a 0.01mm increase for every 10 pieces), the wear of the feeding mechanism (such as the gap of the ball screw) or the fatigue of the sensors should be checked. 
IV. Safety and Maintenance Precautions 
Safety protection 
During the debugging process, protective glasses and gloves must be worn. When the equipment is running, the safety guard cover should be turned off to prevent small hole waste from flying or hands from coming into contact with the die-cutting area. 
The emergency stop button needs to be tested for its sensitivity to ensure that it can immediately shut down the machine when the deviation of the position exceeds the limit, thus avoiding batch scrap. 
Lubrication and Cleaning 
The moving parts of the equipment, such as the guide rails, lead screws, and bearings, need to be lubricated with special lubricating oil (such as precision machine guide rail oil). The amount of oil should be moderate; too much can easily attract dust, while too little will lead to increased wear and tear. 
The lenses of the visual sensors and the cutting edges of the molds should be cleaned regularly with a dust-free cloth dipped in alcohol to prevent the influence of oil stains or waste materials on the detection accuracy. 
Parameter recording and backup 
After the debugging is completed, key parameters (such as pressure, speed, stroke compensation value, and tension value) need to be recorded and backed up in the equipment control system to prevent loss of parameters in case of card change or power outage, thereby reducing the time required for repeated debugging.
